A three-dimensional finite element technique was used to analyze behaviour of laterally loadedrnsingle pile subjected to pure static lateral load. The main objective of this study is to assess therninfluence of the pile diameter, pile length and site condition on the behaviour of laterally...
Investigating the effects of lateral loads in design of foundation is important as comparedrnto axial loads, although it gets normally less consideration in the usual practice. Thisrnstudy investigates the behavior of group piles in terms of load - displacement curves forrntrailing, intermediate...
Expansive soils are worldwide problems that pose several challenges to civil engineers. Suchrnsoils swell when given access to water and shrink when they dry out. The most common andrneconomical method for stabilizing these soils is using admixtures that reduce volumernchanges. This research work...
